Mouth. A cerebellar tremor is low in frequency and high in amplitude. Frequency refers to the speed of the tremor, while amplitude is the degree of movement of the body part.Doctors typically diagnose cerebellar tremors in people with MS and other neurological disorders.Dystonic tremorsDystonic tremors involve involuntary twisting or jerking of the limbs. Certain hand and arm positions may cause the tremors to stop.Dystonic tremors are rare and typically occur in people who are under 50 years of age.Physiologic tremorAll people have an asymptomatic physiologic tremor, a high-frequency, low-amplitude tremor that occurs at rest and during movement.Physiologic tremors typically do not affect a person’s day-to-day activities. However, the following factors may exacerbate this type of tremor:stimulants, such as caffeine and nicotineanxietyfatiguecertain medicationsWhen diagnosing body tremors, a healthcare professional may use physical and neurological examinations, as well as diagnostic tests.Physical and neurological examsThe physical examination involves checking the following:whether muscle contractions occur at rest or during actionwhere the tremor occurs on the bodywhether the tremor is bilateral (on both sides) or unilateral (on one side only)tremor frequency and amplitudeWhen conducting a neurological examination, a healthcare professional will look for the following:increased muscle stiffnessimpaired balancespeech abnormalitiesDiagnostic testsA healthcare professional may also order the following diagnostic tests to determine the cause of body tremors:Blood and urine tests: These tests may help rule out certain causes of body tremors, such as: medication side effectsdrug interactionschronic heavy drinkingthyroid dysfunctionDiagnostic imaging tests: An MRI or CT can help detect any brain damage that may be causing the tremors. A positron emission tomography scan (PET) or a SPECT procedure, where a healthcare professional injects a chemical into the vein, is sometimes appropriate if a doctor believes a person may have Parkinson’s disease.Electromyogram (EMG): EMG tests record electrical activity in the muscles. A doctor may use it to measure involuntary muscle activity in response to nerve stimulation.Specific treatments may help to reduce the frequency and severity of body tremors. What treatment a person receives will depend on the cause, type, and severity of their tremor.MedicationsMedications can help to manage body tremors. The table below shows the different classes of drugs a doctor may prescribe for body tremors, along with examples of each.Nonsurgical proceduresIn some cases, a healthcare professional may recommend a nonsurgical procedure to help manage body tremors.Focused ultrasoundThe thalamus is the part of the brain that controls movement. Damage or disruption to nerve cells in the thalamus
